Sunny, I’m guessing what you mean by “Aragorn has read TAOH” is like he read a like legend based on it because your story is in the same universe but after right? Idk I could be wrong.. but we could just say that the legend Aragorn read wasn’t completely accurate and he doesn’t know exactly what’s going to happen, or maybe he’s just smart enough not to tell them and mess up the timeline, also so what if he does tell them. They can’t get back they are basically alternate reality doplegangers of the ones from the actual TAOH so it’s fine.
